ELECTRIC BAKE OVEN.

Application filed October 2, 1923. Serial No. 666,075.

To zZ-Z whom t may concer/nf:

Be it known that l, Emma LLOYD Gmi- MAN, a citizen ot the United States of America, and resident of the city of Seattle, in the county of King and State of Vilashington, have invented certain new and useful Improvements in Electric Balie Grens, of which the ollowin is a specification.

My invention relates to baking devices and consists oit an oven and a holding` rack therefor of complemental design, so as to be handled together to secure a desirable result.

The object of my invention is to provide an electric bake oven and a rack for holding` the bread, so designed that the work ot operating the oven may be materially reduced.

rllhe features oit my device which l believe to be new and upon which I wish to secure Letters Patent will be herein described and then particularly pointed out in the claim.

The accompanying` drawings show, in diagrammatic torni, the construction ot devices involving my invention.

Figure l is a transverse sectional view of the oven, showing,` a bread holding rack in place.

Figure 2 is a section taken at right angles to that of Figure l, showing a type of oven and rack involving` the same principles but slightly varying in details of construction.

A customary construction ot electric te ovens is one in which the electric hea elements are installed in the ovens in tl' manner resembling the placing' ot ber ot shelves, the same e tendine e ,l across the oven, and at rrequcnt these are combined or associated with the shelves which support the pans in Ywhich the bread is baked. In this type of construction it is necessary that the pans containing;` the bread be inserted and moved about in the oven and then removed therefrom by hand, one at a time. By my pres ent invention l contemplate the einaloyment of bread racks which are movable, upon which the bread may be placed while it is without the oven, and which may be bodily inserted as a whole wit-hin the oven so that the placing of bread within and the removing of the same from the oven is an operation employing only a very few minutes. y

ln the drawings l represents the walls of the oven. These are provided with electric heating` elements in the physical forni ot slabs or shelves, as 2, which are supported from the walls and project into the oven space. In the type of construction shown in Figure l these electric heating elements extend towards but not quite to the center line of the oven. rThese are sepa ated troni each other so as to provide a central free space capable of receiving` the standards or supporting elements of the bread raclr.

hor use with an oven having this central viree space, the bread rack would be coniposed of one or more standards f3, having` feet or base members 30 extending la'tcralliT thereoie a suicient distance to i'iorm a staple support therefor, and with these the supporting shelves or racks 3l upon which the bread is placed. In Figure l l have shown one oit these shelves 31 as havingthereon a set of" bread pans 5. The shelves d3l bread raclt are placed at an elevation that when the rack is inserted into the over., they will be just above the electric heating; elements 2. rThis brings the bread so that it is a short distance below the heatingj'` eloment 2 next above the same.

The floor of the oven is provided with guide rails as e, for the reception or rollers 32 which are placed under the bread rack. This insures accurate placing` of the tray when it is inserted in the oven.

ln the type oif oven shown in Figure the heat-ing; elements 2 are extended fr i the door a sutlicient distance to accommoder 'upporting post 3 of the bread raclr, 'e also, the siufporting shelves Sl ad rack d from the. posts or s `inderds il by one end only, and are positioned so as to lic just above the el wctr'ic heating' elements 2. For this t` )c oit bread rack the i'eet 30 extend forwai dy from the standards, as is clearly shown in Figure ln either form of construction the vertical spacing oi the bread supporting shelves 8l ot the rack and the rearing elements 2, is such that the shelves 3l will pass close above the heating elements 2, and the length of the heating element is su h as to accommodate the vertical posts or supporting standards ot the rack.

By employing` an oven and racks oir this character it is possible to load the racks While they are out of the oven, under conditions in which it is comfortable to work. In charging the oven the door is opened and unsupported edge spaced from the wall at distance to accommodate rack standards, und carrying' racks having a supporting base,

Standards 'ataone side of the base tray carrying racks extending horizontally from the `'stendardi said racks being vertically Spaced to clear the heat-ing elements and the standards to be in the space at the unsupported edges of the heating element.
